Gastrointestinal Microbiome Study of Appendiceal Cancer

Not Applicable

Recruiting

• Conditions: Pseudomyxoma Peritonei; Appendiceal Neoplasm; Cancer, Appendiceal

• Registration Number: NCT02599116
• Lead Sponsor: Mercy Medical Center

Brief Summary

This study analyzes the gastrointestinal microbiome of appendiceal cancer patients with peritoneal spread scheduled to undergo cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). Participants will provide fecal samples pre- and post-operatively.

Detailed Description

Analysis of the human microbiome is an attempt to define how changes in the human microbiome are associated with health or disease.

Eligible participants scheduled to undergo cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for appendiceal cancer will provide fecal samples pre- and post-operatively. Investigators will analyze potential changes in the gastrointestinal microbiome and make comparisons to an age-matched healthy sample.
